1/4” compress female to 1/4-40 male
« on: March 22, 2024, 11:18:01 pm »
So I am wanting to run the 1/4” compression fitting which uses a female attachment on top of the Jensen boiler, and union or run it down to 1/4-40 UST, for PM research piping.

Can anyone help me figure out what I need?  I have searched for 1/4” compression threading to 1/4-40 but can’t get clear answers.

I ordered this on eBay.

However, the Jensen threads are 5/16-24,  this is 5/16-27…. I’ll try it. It’s only a few bucks. [ Guests cannot view attachments ]

since the threading is 27 tpi & NOT 24 tpi, you'll ruin the threads in the Jensen boiler if you force it in.

Well, damn.   I can’t believe it is that close to what’s needed.     Any idea what I need in order to achieve what I am seeking?

Will not only ruin the Jensen threads... there is no flange for a gasket.

How can I connect PM 1/4-40 to 5/16-24?

Probably have to go with special machining.

Can you hook me up? How much do I need to pay you.
